Stainless steel fasteners are used extensively throughout industry for both original equipment manufacture as well as for replacement. The stainless steel fastener materials are identified as the B8 class of alloys and are identified in the ASTM Specification A193/193M (Standard Specification for Alloy Steel and Stainless Steel Bolting Materials for High Temperature Service). The corresponding nut specification is ASTM Specification A194/194M.

Our Stainless Steel Fastener plant is equipped with various testing facilities like Tensile Testing Machine also known as tension testing. We also conduct other tests like Hardness Test, IGC Test, Positive Material Identification Test to ensure that all the product going out of our manufacturing plant are the best in terms of quality.

Marking & Shipping Of 317 Stainless Steel Screw

• Packaging
In generally, If you have no special requirement, we will use the mass packing (bag carbon tray). If you want to do the special packing, please advise us the specific details, pictures or design.

Fast delivery and best packaging

Wooden Box, SUITABLE BAGES OR BOXES

Delivery Detail: 7-15 Days

• Shipping
In generally, our customer often request to delivery by express, plane or sea. Any other better way will be also accepted well.

• Location
Our facility is located a few miles from the Port of Nhava Sheva (Mumbai), the India’s Commercially Important port for foreign waterborne tonnage, and one hour from the Sahara international Airport. Our close proximity to these vital ports along with the speed in which we can process and pack international orders allows us to deliver anywhere in the world within few days.
For domestic shipments, close proximity to interstate highways and rails allow us to provide competitive inland transportation to all over India destinations and ports.

317l is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

corrosion resistance

317l has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. increased levels of chromium, nickel and molybdenum compared to 316l stainless steel improve resistance to chloride pitting and general corrosion. resistance increases with molybdenum alloy content. 317l is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°f (49°c). at temperatures under 100°f (38°c) this alloy has excellent resistance to solutions of higher concentration. however, service tests are recommended to account for the affects of specific operating conditions that may affect corrosion behavior. in processes where condensation of sulfur-bearing gases occurs, 317l is much more resistant to attack at the point of condensation than conventional alloy 316. the acid concentration has a marked influence on the rate of attack in such environments and should be carefully determined by service tests.

welding 317l

317l is readily welded by a full range of conventional welding procedures (except oxyacetylene). aws e317l/er317l filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of 317l, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of 317l should be used to weld 317l steel.
